Graph B represents the velocity of the sphere changes over time when falling with constant acceleration.
- Acceleration is the measure of how quickly a body's velocity varies with regard to time, and constant acceleration occurs when a body's velocity changes proportionately over a period of time, or at a constant rate. It measures in m/s2.
- It is claimed that a body has continual positive acceleration when it begins to move with an initial velocity of zero and gradually increases to a positive value over time.
- Constant positive acceleration is demonstrated by a ball falling freely in a vertical direction.

Answer:
C)a lack of supporting empirical evidence
Explanation:
A scientific reasoning can be rendered invalid if empirical evidences are lacking. Empirical evidences are usually a product of observations or experiments.
When these are lacking or cannot be gathered, scientific observations or sometimes reasoning can be rendered as invalid because there is no ground to prove them.
